Q 25. How to enable "Search Engine Friendly" (SEF) URLs when running Joomla using the server URL?

Rename the file "htaccess.txt" in your Joomla!'s base folder to ".htaccess".

This step may not be necessary. Open .htaccess in a text editor. Uncomment RewriteBase / (remove the first character, #). If Joomla is installed in its own folder, the enter the Joomla folder name after the forward slash. e.g. RewriteBase /yourjoomlafolder.

Log on to your Back-end and open the Global Configuration.

Enable the Use Apache mod_rewrite/URL rewriting option and Save. This option uses the Apache mod_rewrite function to eliminate the "index.php" portion of the URL.

Check if your site works correctly. Your URLs should now look like:
http://www.example.com/the-­news/1­-latest-­news/1-­welcome-­to­-joomla

If this option causes errors, please see How to check if mod rewrite is enabled on your server.
If it is not enabled and you have access to the file apache/conf/httpd.conf, open that file and check if the line LoadModule rewrite_module modules/mod_rewrite.so is uncommented. If necessary, uncomment the line and restart the Apache web server.
If mod_rewrite cannot be enabled, leave this option off. It does not matter if you leave the .htaccess file renamed.

If you think this necessary, enable Add suffix to URLs and Save. This option adds .html to the end of URLs. There are different opinions on whether this is necessary or even useful. Search engines do not seem to care if your URLs end in .html or not.

Open the Plugin Manager and enable the System - SEF plugin. This plugin adds SEF support to links in your Joomla articles. It operates directly on the HTML and does not require a special tag.
